cnnnm-snrnna'ronn Specification of Letters Patent. I Patented Oct). 26, 1909.

Application filed September 23, 1908. Serial No. 454,374. I

To all whom it may concern:

Be it known that I, KNUT' O. A; CAnnssoN,

a oitizen of the United States,- and a resident of Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Cream-Separa-' tors, of which the following is a, full, clear, and exact description.

This invention relates more particularly to a centrifugal separator adapted to sepa-' rate the cream from milk- The primary object of the invention is to provide a simple and efiicient separator in which the 'milk or other 'liqnidfrom which the constitucntparts are to be separated from" each other may be passed or forced through the separator under pressure ,or by gravlty in such a way as to compel the same to take a zigzag course through the se arator while a part thereof is rotated, an at-the same time provide eiiective means for collecting the, cream and separating it' from the milk so that'they will not again commingle or become mixed, thus efiecting a complete sepa ration of the cream and overcoming many of the objections incident toflse'parators as ordinarily constructed.

further objectof' the invention is to provide a separator which may be easily constructed and assembled, and which has great capacity for separating cream from the milk with a. minimum amount ofspace required therefor. j

With these and, other objects inview,'the invention will be hereinafter more particularly'described with reference to the accompanying drawings, which form a part of this specification, and will then-be'fpo'inted out in the claims atthe end of'the description.

In the drawings, Figure 1 is averticat section taken centrally on the short axis of thedivision members of one form of scparator embodying my invention. Fig. 2 isv a sectional plan view, taken von a line II -II' of Fig. 1; and Fig. 3 is a detail view of one of the division members.

While I shall describe the invention as unore particularly adapted for separating cream from milk, it will be understood that the invention is equally applicable for the separation of othercompound liquids. into their constituent elements.

The casing 10 may be of suitable construction, and may comprise a body part or member 11 which is'substantially cup-shaped in form, and a base member 12, and from the base member 12 may project a sleeve or tubular part 13 the upper end of which is tween the two members. The'sleeve or tubular part 13 of the member-or base 12 has a 'tapered' opening 19in which is adaptedto fitthe tapered end.20 of'a shaft 21 which 1 may be connected with anysuitable driving means whereby the said separator casing may-be rotated at a high 'spoed, and above I the end '20 of the shaft21,isa partition 22, a 7 above which isa pipe or. connection 23 whichserves as a source of supply'gfori the milk? orotherliquid. The connection 23fits into the upper'open end of the sleeve or part'13,

and is normally held stationary, and where it fits within the open end ,of the part 13 may be provided with a plurality of openings 24 for the milk or liquid to pass therethrough'so as to. serve as ameans for lubri-. eating the bear ng surface bOtWOQIlI the part 13- and the connection 23. This connection 23 is provided with a beveled part 25 serving as a valve which engages the beveled end or sent 26 in the upper end of the part 13, and said connection 23 is normally forced downward by means of a spring 27 arranged around the connection 23 and interposed between a shoulder on said connection and the under surface of a fixed cap or cover .28.

the said connection being held tothe. cover by means of a key 2901' in any other desired way. A pipe 30 leading to the source of supply is held to the upper end of the counect1on 23 by means of a coupling 31; a part of which is tllft 'ided and engages the threaded end of the connection 23 and made to force the end of the pipe 30 into engagement with the onter end of'- the'conn'ectlon 23 to provide a tlght joint therewith.

To cause the milkto take a zigzag course and to properly separate the" cream from the milk, I provide within the casing a plurality of division members 32. members may be of any desired number and may be substantially oval or elliptical or any other desired form, and concentrically arranged with respect to the other. I prefer to use a number of the division members, and each of said division members at the shortest axis or diameter thereof is provided with an inwardly-extending and substan- H tially V-shaped part or depressed portion 33,

and in these depressed portions are slots or openings 34. The openings or slots 34 of each division member alternate with, respect to members adjacent thereto. ;That is the slots or openings of one member are near the top thereof, while the slots in the next member are at the bottom so that the liquid must take'a zigzag course through the spaces formed bythe several division members and pass alternately upward. and downward be tween said members, and by reason of the.

fact that the openings 34 are nearest the center, the cream will collect at these points, while the skimmed or blue milk will pass through the openings 35 arranged at the -points of the greater axis or diameter ofsaid members. -These slots or openings 35 are also alternately arranged so as to cause the milk or liquid to take a zigzag course at intervals apart,,an' l said ribs or.,project-- ing parts serve to hold the different sections or division members the proper distance.

apart, and further to keep the milk evenly 'distributed over the surface of said mem- 'bers. The sleeve or part 13 of the casing is provided with one or more openings 38', for the milk from the source of supply to pass within the casing to the space between the i1 inermost division member and said part 13, and-as tlxe cas ng rotated, the liquid while being forced under pressure through the spacesliu' wcen the division members, or by "gravity if-desired, will cause the liquid to pass in a zigzag way between the several divis on inen'lbers, the'blue or skimmed milk by reason .of gravity will pass-through the openings 35, in the members,'while the cream will collect at the parts.33,]anid will pass through the openings 34 into the channels or grooves 39' formed in thel undersur face of a cap or cover 40. Said grooves 39 These division are two narrow grooveshaped channels radially and oppositely disposed in the undersurface of said cap 40. This cap or cover" I is normally forced downward against the upper edges of the division members by means of a spring 41 arranged around the part 13, and interposed between the-cover or deflector 42, and said cap piece or cover 40. The cream thus passes through the cover. 40 through the channels 39 and openings 43 under the cap 42, while the skimmed milk in passing through theopenings 35 will pass out of the space between the outer division member and said cover'40, the latter being. cut away, at '44, atits greatest diameter for-this purpose.

The cover or deflector 42 has its body 45 provided with a plurality of depressed parts or protuberances 46 which hold thesaid' body portion asuitable distance away. from the under surface of the top 47 of'the casing member 11,.to provide a space 47? for the skimmed milk topass between the body portion and the top 47 after the'milkpasses through. the openings 35nof'the outer division member, This deflector or device 42 is provided with an upi'vardly-proje cting tubular part 48 which is. adapted to fit with- I in a ring or tubular device 49 secured within the upper portion of the casing member 11. The said tubular part 48 and member 49 into which. the former fits provides an. an-

nular space 50 around the same formin a cont nuatlon ofthe space 47, and which communicates with one ormore openings5l in the ca sing member whereby the milk'maychamber 50, and out of the openings 51 between the hoods'or deflectors 52 and 53 which form a space around thecasi-ng. at the upper portion thereof.

openings 54 to and through the opening 55 tween the hood or deflector 53 and part 56 of the cover 58, both the cream andthe milk being deposited in suitable receptacles provided therefor ifdesired.

I t will thus be seen that the milk or other liquid to be separated into its constituent parts may be passed either by gravity or.

under a more or lesshigh pressure from the source of supply. to the tubular,v part 30 through the tubular part 13 of the Casing, and byreason'of the partition 22 will be deflected through the openings 38 into the space between the inner division members,-

and willpass in a zigzag way through the spaces between the several division gmembers, the cream collecting toward the center and atthe parts 33, so as to pass'thrbglgh the 11 0 1 of the cap or nut.15, and in the space be- T pass through the-space'47 into the space or I The cream'after passing through the openlugs 43 of the cover 40, will pass upwardwithin the tubular part 48 of the deflector or device 42, and out through one or more 34, and through the opening 43 upward and outward through the openings 54 and 55, while the blue milk or other part of the liquid will pass through the openings openings 35 in v a zigzag way through the spaces bedi-vision members and out Fig. 2, through opening 51, be-

tween the several through the openings'e i, the space 47 chamber 50, tween'the hoods or devices 52 and 53, thus preventing the cream and milk after once being separated from again commingling.

Where the word elliptical or oval 7 is used in connection with the form of the division. members, it'is to be understood that the terms are used in their broadest sense to include members which are longer one way than another though the insertion is not limited to. this'particular' form of division member.

J ments and in case of milk substantially every From the foregoing will be seen that a simple and milk and other liquids in which the liquid efficient separator is provided for maybe forced through the separator under pressure, or may be made to pass there-4 through by gravity and the movement of the machine itself; that by providing the division members as shown, the liquid will be thoroughly separated into its constituent elearticle of the cream will be separated thererom; thatby this means the separator may be made veryv compact and of a much less size than. 1s required forthe' s'amecapacity ofseparator bythe' ordinary method of septhe'cream'from'the milk, and that arating so constructed that they ma the parts are be readily made and easily assembled.

Having thus described my invention, 1
